Abstract
Synopsis Total moisture storage and moisture distribution in the top 4 feet of a Pullman silty clay loam profile were not affected by tillage and weed control practices. Three methods of fallow (disking, subsurface tillage and chemical weed control) were highly inefficient in storing precipitation. When weeds were properly controlled the efficiency of moisture storage under chemical fallow was equal to that under subsurface tillage.
